Abstract
The utility model provides a special lock for a double acting door, which relates to the field of the production technology of door locks. A lock tongue transmission part comprises a set of a gear and rack bar transmission device. The lock tongue is a rack bar-shaped lock bolt. When the double acting door is opened or closed, a transmission sheet (8) in a lock head drives a rotating block (5) to rotate. Two pins (4) which are inserted in the rotating block (5) further drives a gear (2) to rotate. The gear (2) pulls out the rack bar which is a lock bolt (15) to lock a door lock. As long as a key is rotated for one circle, the door bolt can extend out with a length of more than 11 centimeters. The utility model overcomes the defects that the existing built-in lock of a common a single door can screw out the lock tongue with a length of about two centimeters after the built-in lock is rotated for one circle, and a double door can not be locked.
Description
The utility model provides a kind of special-purpose built-in lock of double door, belongs to the door lock production technical field.
Present dark formula door lock is all at the single open-door design with produce, and this door lock has a kind of inclined-plane dead bolt that only is provided with, and is another kind of then on the basis that is provided with the inclined-plane dead bolt, also have additional a rectangle dead bolt.When using this door lock in back, one close conveniently, the inclined-plane dead bolt just springs in the glossal canal on the doorframe, and door is lockable.For the sake of assurance, insert in the key groove with key again, revolve and turn around or two circle or three circles, the rectangle dead bolt is entered in the microscler lock tongue slot.Turn around but whenever revolve, the rectangle dead bolt can only stretch out the length about 2 centimetres.When this tapered end is used for locking double door, because inclined-plane dead bolt and rectangle dead bolt extend into the curtailment in the lock tongue slot, one push away gently, two fan doors just are open.At this moment, wherein the Yishanmen page or leaf is shut earlier often, and the upper and lower cotter joint at the door leaf back side is inserted, and other Yishanmen is shut again.It is sealed that double door is become single open-door, just can prove effective, and be very much time-consuming bothersome but lock a door at every turn.Some people, externally props up with a long iron and crosses after double door closes simply without built-in lock, adds padlock again.Diminish attractive in appearance so again.
The purpose of this utility model is the built-in lock that a kind of double door special use will be provided, and at closing time, turns around as long as key revolved, and just can make dead bolt stretch out length more than 10 centimetres, and reaching that key turns around just can be the purpose of double door pinning.Enter the back as long as firmly draw reverse rotation one circle can in doors door lock be lived again in back one to turn-knob.
The purpose of this utility model is realized like this: the special-purpose lock of double door, comprise tapered end part, dead bolt and driving section thereof, dead bolt is a rooted tooth shape long-bar metal bolt (15), the tooth of bolt (15) and top gear (2) engagement, the inner ring of gear (2) is interference fit and core wheel (3) links, two end faces of core wheel (3) are fitted with switch block (5) and turn-knob (6) respectively, and two pins (4) pass switch block (5) and turn-knob (6), and an end of pin (4) embeds in the turn-knob (6); The center of switch block (5) is inserted with driver blade (8).
Two through holes that pin (4) is passed through in the middle of the switch block (5) all are in same plane, this plane by switch block (5) the center of circle and perpendicular to the end face of switch block (5), but the center of circle of the relative switch block of two through hole and asymmetric.
The shell of dead bolt driving section (1), gear location-plate (7), rack tube (16), secondary rack tube (17) all are fixed on above the door leaf (9); Shell (1) except that be provided with protrude partly to gear (2) spacing, also be drilled with a screw and be equipped with and carry out spacing to turn-knob (6) in the spill circular groove that screw (13) stretches into turn-knob (6).Part (14) is the trip bolt of shell (1).
Turn-knob (6) spill circular groove bottom necessarily is inserted into the central length d of switch block (5) greater than pin (4) to the distance D of bolt (13) side.
Core wheel (3) is penetrated with a through hole with the center of turn-knob (6), and the end that extension spring (10), extension spring (10) are housed in the through hole is fixed on the core wheel (3), and the other end is fixed on the spring support (11) of turn-knob, and spring support (11) is covered by capping (12).
Bolt (15) can be that castellated strips is cylindrical, also can be castellated strips rectangle etc.
The utility model is described in further detail below in conjunction with accompanying drawing and using method.
Fig. 1 is for omitting tapered end part back structural representation of the present utility model.
Fig. 2 is for omitting tapered end part and driver blade (8) scheme of installation of the present utility model afterwards.
When going out to lock a door, insert key counter rotation one circle, driver blade this moment (8) drives switch block (5) rotation, the pin (4) that inserts in switch block (5) through hole drives core wheel (3) simultaneously and rotates with turn-knob (6), because core wheel (3) is an interference fit with gear (2), gear (2) is also promptly followed rotation, thereby also is tooth bar that bolt (15) along continuous straight runs advances to the right.Gear of the present utility model is chosen the number of teeth 25 teeth, modulus 1.5, be deep into secondary tooth cover (17) when bolt length can reach more than 110 millimeters, so door lock is lived.Long dead bolt also is the sufficient length of profile of tooth bolt, and what overcome that the common door built-in lock exists whenever revolves the defective that a circle keyed deadbolt can only be stretched out 20 mm lengths, has guaranteed that double door is not open.Equally, when going into the room, the key clockwise direction revolved to turn around just can open door.
Go into behind the house double door is shut, pull out turn-knob (6), because D is greater than d among the figure (1), pin (4) has withdrawed from two jacks of switch block (5), again with 360 ° of turn-knob (6) clockwise direction rotations, pin (4) again driven gear to drive tooth bar more also be that bolt stretches out more than 110 millimeters, thereby again door lock has been lived in doors.Two through holes being opened on the switch block (5) are in same plane, and this plane is by the center of circle of switch block (5) and perpendicular to the switch block end face, but two relative centers of circle of through hole and asymmetric.She Ji purpose like this is in order to prevent turn-knob (6) when rotating to 180 °, and pin (4) falls into the other side's jack mutually.If like this, bolt (15) stretch out extended length when partly just having only 360 ° of rotations half.Bolt length stretches into deficiency, and double door just is easy to be open.
Be to increase back locking function, also promptly when the people the indoor people who prevents to be furnished with identical keys again from outside open double door and go into when interior, the utility model also is furnished with one of common door lock and overlaps anti-lock device.
The utility model design is unique, and is easy and simple to handle, firmly practical, for the exploitation and the production of Lock for two-wind door provides prospects brighten.
